Hi! i need with the question: why is the dead sea so full of minerals?

The Dead Sea is a terminus for the flow of rain and surface water, which means water flows into it but doesn’t flow out: its water has no escape, but is trapped to evaporate. Soaring summer temperatures and year-round hot dry climatic conditions make it a perfect place to spend unforgettable holidays yet lead to significant losses of water to evaporation. The water has been losing its H2O content for 65,000 years, with the minerals becoming more and more concentrated and salt prominent among them.

this statement is true.

forests are public goods, available for everybody. when usage of such a good becomes interesting for consumers and its usage increases, there can be a risk of overexploitation. it is a non rival good therefore, if one person consumes the good it does not reduce the availability for subsequent consumers.

these caracteristics require the establishment of measures in order to prevent the destruction of a commonly owned space, for example, to restrict the amount of people that have access to the same time.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
